Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a fountain device illuminated by optical fibers.

(Prior art) As a fountain device with a lighting function to make the fountain more decorative, for example,
There is one described in Publication No. 49029.

Conventionally, fountain devices with this type of lighting function were
Fountains are generally designed to be illuminated by underwater light sources at night and in dark places, but lighting from underwater has the disadvantage that the entire fountain becomes blurred, and there is also the risk of electrical leakage. Furthermore, it was impossible to cause the injection nozzle itself to emit light, and the lighting effect was dissatisfied.

In addition, in the case of underwater lights, the purpose is to make the water sprayed from the nozzles glow rather than to make the injection nozzles shine, so it is not possible to make each nozzle shine clearly, and there are complaints that the decoration is not sufficient. It was hot.

(Problems to be solved by the invention) This invention was made to solve the above-mentioned conventional problems, and its purpose is to be able to clearly illuminate both the fountain and the nozzle without the risk of electrical leakage. Our purpose is to provide fountain equipment.

(Means for Solving the Problems) The present invention is a plastic light beam having a double structure consisting of a cylindrical nozzle that sprays water, and a number of sheath materials and core materials attached to the outer circumferential surface of the nozzle. and an illumination device having an external light source that supplies decorative light to these optical fibers from a starting end side of each optical fiber, and a terminal end of each optical fiber is configured to illuminate water spouted from the nozzle. , the sheath material is peeled off at a desired portion of each optical fiber located near the periphery of the nozzle, which is located at approximately the same level as the opening end of the nozzle; This is a fountain device with an exposed core material.

(Function) The external light source of the lighting device is placed outside the water,
the optical fiber obtains light from this external light source;
The opposite end side illuminates the side of the nozzle and the water spouted from the nozzle.

(Example) Hereinafter, the present invention will be described based on an example shown in the drawings. 1 to 5, the fountain device according to the present invention has a nozzle 1 for spraying water upward.
, a large number of plastic optical fibers 2 attached over the entire outer peripheral surface of the nozzle 1, and an illumination device 4 having an external light source that supplies decorative light from the starting end 3 side of each optical fiber 2. ing.

The nozzle 1 is an existing one, and a required water pressure source is provided upstream thereof. Further, the optical fiber 2 has a sheath material 6 and a core material 7 as shown in FIG.
They are of a type having a double structure, and are arranged in a row around the nozzle 1 in close proximity to each other and substantially parallel to each other, with their longitudinal directions along the axial direction of the nozzle 1.

The terminal end 8 of each optical fiber 2 is positioned approximately at the same level as the open end 9 of the nozzle 1 so as to illuminate the water jetting from the nozzle 1. Furthermore, in a desired portion of each optical fiber 2 located near the periphery of the nozzle 1, the sheath material 6 is partially peeled off or scratched, and the core material is 7 is exposed. To fix the optical fiber 2 to the nozzle 1, it may be directly attached using an adhesive or the like, or it may be attached to the outer periphery of the mounting tube member 10 in advance as shown in FIG. may be fitted around the nozzle 1. Furthermore, as shown in FIG. 7, the outer periphery of the optical fiber 2 may be protected by a transparent cylindrical member 12.

On the other hand, the illumination device 4 includes an existing general halogen lamp or the like as an external light source. In another embodiment, the illumination device 4 includes a translucent colored plate 11 such as a colored lens between the external light source and the starting end 3 of each optical fiber 2 in order to add a desired color to the light from the external light source. (Fig. 3) may also be provided.

To explain an example of how to use the fountain device configured as described above, the nozzle 1 is installed in a desired aquarium or the like as usual, and the external light source of the lighting device 4 is placed on land away from the nozzle 1 (in the present invention). installed outside the aquarium). Therefore, the starting end 3 side of the optical fiber 2 is exposed on land, the starting end 8 side is projected upward from the water together with the tip of the nozzle 1, and a part of the middle part of the optical fiber 2 is buried in the water in the water tank. be done. If water is jetted from the nozzle 1 in this state, the optical fiber 2 will receive light from the illumination device 4,
As shown in FIGS. 3 and 5, both the side surface of the nozzle 1 and the water spouted from the nozzle 1 are illuminated. As a result, the decorative effect of the fountain device is improved. Moreover, as shown in FIG. 6, the mounting cylinder member 1
When the optical fiber 2 is attached to the nozzle 1 through the nozzle 0, the attachment of the optical fiber 2 becomes extremely easy when the nozzle 1 is already fixed and difficult to remove.

(Effect of the invention) As described above, according to the invention, the terminal end of the optical fiber illuminates both the side of the nozzle and the water spouted from the nozzle, and the starting end of the optical fiber illuminates an external light source. Since the fountain device has a configuration in which decorative light is obtained from the lighting device, it is possible to improve the decorative effect around the nozzle, and the fountain device can be installed outside the water to avoid the problem of electrical leakage. can get.
